My mechanic has moaned his bag off that i bought febi and not powerflex because they are a pain to fit, and hes put off fitting them for this reason which i why im still driving round with my coilovers in the boot. i did alot of searching before i bought them and yes alot of people said it makes the ride harsher, so because its for my daily i went with the majority and bought OE. It will end up costing me more to do so as any money i saved on the bushes it will cost me double in fitting.
I'm not disagreeing with you EssThree, you prob drive yours harder than i do so you will appreciate the more precise feeling it gives you.
My rear shocks are shot anyway so theres no harsher ride than mine at the moment, banging over the slightest bumps! can't wait for my suspension swap in a week or so.
